User question: What are the reasons for the bright spot of EL test? Initially, the components were lighter, but after the components were installed and operated for a period of time, the bright spots became heavier and the power was attenuated.
User BMR answers: The bright spot may be caused by the following reasons: 1. If the battery is cold-welded, the position of the EL grid will be bright;
2. The structure of the cell itself will lead to leakage, and the position of leakage will be bright.
The bright spot will become brighter and brighter. The operation of the module itself is a process. The current operation is definitely where the resistance is flowing from where it is small. In the initial stage of operation, the place with low resistance is not found. It is not very bright. Since the bright area is leaking, the relative resistance is low. The current will be concentrated in this area, and it will take a long time. Naturally, this place will become brighter and brighter. It will be bright and shading, and it will also generate heat. The natural attenuation will be great.
From the figure, there are several films in the first image that belong to the highly efficient film, and some of them are invisible. The bright picture in the second picture is first identified as a high-efficiency slice mixed into a low-efficiency slice (relatively). Of course, there appears to be a live line (the upper one).
In addition, sorting, single-welding, string welding and other processes during the production of components may cause leakage.
Compared with mini piston vacuum pump, mini piston air pump outputs positive pressure.
Mini piston air pumps are small, compact and efficient devices that are designed to deliver a continuous and reliable supply of compressed air. These pumps are commonly used in a variety of applications, including medical equipment, laboratory instruments, aquariums, and air mattresses. Mini piston air pumps are classified based on their operating principles, design, and performance. Some of the common types of mini piston air pumps include: 1. Single-acting Piston Pump: This type of pump uses a single piston to compress the air and deliver it through the outlet. The piston moves in one direction only, and the air is drawn in through the inlet during the return stroke. 2. Mini Diaphragm Pump: This type of pump uses a flexible diaphragm to compress the air. The diaphragm moves back and forth, creating a vacuum on one side and compressed air on the other side. The vane moves in and out of a chamber, creating a continuous flow of compressed air. Mini piston air pumps can also be classified based on their performance, such as flow rate, pressure range, and power consumption. These pumps are available in different sizes and configurations to meet the specific requirements of different applications.
